About Service Records 
 
An SRV record holds the following information: 
•  Service: the symbolic name of the desired service.  
•  Protocol: this is usually either TCP or UDP.  
•  Domain name: the domain for which this record is valid.  
•  TTL: standard DNS time to live field.  
•  Class: standard DNS class field (this is always IN).  
•  Priority: the priority of the target host.  
•  Weight: A relative weight for records with the same priority.  
•  Port: the TCP or UDP port on which the service is to be found.  
•  Target: the hostname of the machine providing the service.  
 
An example SRV record might look like this: 
 
_sip._tcp.example.com 86400 IN SRV 0 5 5060 sipserver.example.com. 
 
This expression denotes a server named sipserver.example.com. This server listens on 
TCP port 5060 for SIP protocol connections.  The priority given here is 0, and the 
weight is 5. 
 
TDM Routing Option  Parameter 
fields
 
 
Use TDM 
Routing for 
Intra-Gateway 
calls  
Y/N; 
enabled by 
default 
Allows calls placed 
between ports on the 
same MultiVOIP voice 
channel board to be 
routed over internal 
Time Division Multiplex 
bus without conversion 
to IP. TDM routing 
effectively eliminates the 
delay introduced by IP 
conversion. 
If you require all calls to 
be IP routed, disable the 
“use TDM Routing for 
Intra-Gateway Calls” 
option. Since this is not 
normally required, we 
generally recommend 
leaving TDM Routing 
enabled.
